In the extraction by flushing a fluid flows through the inside of a closed component to detach the particles of the wetted inner surface and to drag them out.
The method is the practical simulation of a flow-through process. It is use for parts like:
- Heat exchangers
- Transmissions etc..
Here are the particles collected on a membrane and analyzed.
The characteristic parameters such as flow rate, amount of fluid, flushing pressure and flushing time are determinate by the decay curve
